The Economical Control of Infectious Diseases
Posted: 1 Jun 2004
The structure of representative agents and decentralisation of the social planner's problem provide a framework for the economics of infection and associated externalities. Optimal implementation of prevention and therapy depends on: (1) biology including whether infection is person to person or by vectors; (2) whether the infected progress to recovery and susceptibility, immunity, or death; (3) costs of interventions; (4) whether interventions target everyone, the uninfected, the infected, or contacts between the two; (5) individual behaviour leading to two types of externalities. By way of example, if people recover to be susceptible, government subsidies should equally favour prevention and therapy.
